I've been looking into OLED displays (namely the 128x64 SSD1306) as an alternative to the 16x2 LCD module (HD44780) I'm currently using. You can actually pick them up for around $4AUD. From what I've seen they use less GPIO pins than HD44780 LCDs.

Has anyone had a go with OLED displays? Thoughts? I'm super keen to make use of the extra pixels - and images!
